摘　　要：在最不利工况下,选用合理的单元对渡槽进行结构计算,得到的节点应力和位移云图显示了槽身出现最不利变形和最大拉、压应力的位置。结果表明:槽身的后浇带处、主梁支座钢绞线附近、两侧边墙与底板连接处的变形比较严重。另外还将计算结果与槽体内埋设的精密安全监测仪器所测的数据进行对比,其结论对类似工程的设计和施工有重要的参考意义。Based on the most unfavorable conditions,the paper analyzed the structure calculation on a reasonable structure of the aqueduct unit. The node stress and displacement diagram displayed the position on the body where the most unfavorable deformation and the maximum compressive stress exist. The results showed that the serious distortion occurs in the body of post-cast strip,the bearing steel girder nearby,the joints of the sidewalls and slab. This paper also compared the calculated results and the data measured by the precise monitoring instruments buried in the aqueduct ,the conclusion has an important guiding significance for the design and construction of the similar engineering.
